A "Chingasm" is the extremely fast movement of the chin and/or throat area. Although the causes of chingasms are unclear, it is now confirmed that a loose jaw bone could be the source of a chingasm. A chingasm is mildly painful and attained through an outragous amount of laughter. Chingasms have a semi-fatigueing affect on an individual, leaving them breathless and possibly tired after the climax of the chingasm. If an individual attempts to talk during a chingasm, the words will come out separated, and nearly illegible. It has also been proven that during a chingasm, the chin/throat is moving at such a velocity that low resolution videocameras are not able to capture it.

David: "Yeah, she has those like every day."
